Many of us do, Sunshine. But if I may be so intrusive, I presume that you are a lot like myself in this regard, in that you probably also worry much more about going so far in the opposite direction trying to correct your deficit in self-confidence (and consequently putting yourself down) that you become arrogant, narcissistic, and judgmental of others. And since that is the worse extreme end of the spectrum to you, your fear of becoming that keeps you at the opposite end (low self-confidence and constant self-debasing).
If I pretty much got this right about you - and it is not my intention to be condescending to you in making this assumption about you, just my attempt to empathize and make you feel better - then I understand. I myself always figured that, if I have such a problem finding the proper balance between the two extremes, then I would still rather be on the end of self-debasing and being too much of a pushover, for I consider the opposite end (general arrogance and narcissism) to be a much, much greater evil. I know it isn't much, but all I can suggest to you is that you pray to the Lord to give you the right balance in this and all other things in life.
